We report a calculation of the absorption coefficient of donor impurities located at the center of a quasi-1D GaAs quantum well wire with finite confinement potential as a function of photon energies for different wire widths. The theory has been formulated by using suitable variational wave functio
Polarizabilities of shallow donors and acceptors in infinite-barrier GaAs/Ga \V Al V As quantum wells have been calculated using the Hasse variational method within the effective mass approximation. The effect of spatially dependent screening on polarizabilities is taken into account with an r-depen
